Hi Puneet!
I am working on speech recognition and using Sphinx 4, i am trying to execute system commands like running an exe file using voice command. I read out d specifications of Sphinx and can now run Hello World Demo effectively. But still i am unable to add new words to it. For e.g. I want to add Open and Close commands to grammer, I edited d gram file for same but my prog still printing words from good morning | hello etc those were specfied in prev .gram file. I read smwhr that it can be done wid Apache Ant, but i am unable to figure out how to do so..? Please Help !!

Thanx for your marvelous guidelines. I did expanded my acoustic model to recognize extra words. But my problem is that i cant run the project. the displayed errors are:

Exception in thread “main” java.lang.NullPointerException
at edu.cmu.sphinx.util.props.SaxLoader.load(SaxLoader.java:74)
at edu.cmu.sphinx.util.props.ConfigurationManager.(ConfigurationManager.java:58)
at edu.cmu.sphinx.demo.helloworld.HelloWorld.main(HelloWorld.java:33)

I didn’t included the HelloWorld.jar in sphinx library,If I did the application only recognizes the words ‘hello will’ etc as in the demo. Please help me with this its very important for my academics

Hi, is there any possibility to make Sphinx ignore words which are unknown to the Dictionary, so I can ommit Warnings like this:

14:37:14.732 WARNING dictionary Missing word: &
14:37:14.732 WARNING jsgfGrammar Can’t find pronunciation for &
14:37:14.732 WARNING dictionary Missing word: tammi
14:37:14.732 WARNING jsgfGrammar Can’t find pronunciation for Tammi
14:37:14.733 WARNING dictionary Missing word: -

I just want to play dynamically addes mp3s by titles, so Sphinx should recognize spoken track-titles even if some parts of them are ignored (titles usually differ enough). Thanks for help

Hello,
I was wondering the same you previously asked, Ashish. Maybe you’ve got the answers now and you can help me.

Is it possible to make sphinx recognize all the words from its vocabulary without including them in the grammar?

Or if I have always to use a grammar then how can I make the grammar to recognize eveything a user says (all the words in my dictionary)?

I’m using a spanish acoustic model with Sphinx, but it only recognizes what it is on my gram archive.

Thanks for your help!

Hey Ashish,

Thanks for reply,
I believe it will not be as simple as you have mentioned. You will be interacting with 3rd party application for that and OS will also play major role here. Simply opening or redirection will not be enough as opening it every time in new window will look make it messy. So basically you will have to gain control over the “Web browser” no matter which one you are going to use. That can be done through processes or using their specific API.

Hope that works !
